. Adult (

c) with wingspan
11.5 mm
. Head pale yellowish brown. Antenna pale yellow. Labial palpus with second segment yellowish white, blackish brown on outer surface, pale yellow apically; third segment creamy white on inner surface, ocherous brown on outer surface. Thorax and tegula grayish brown; patagium yellowish brown. Forewing with costal margin almost straight, apex protruding triangularly, termen oblique; ground colour grayish brown; markings blackish brown: costal patch at middle, wedge-shaped; median patch rectangular, extending from upper margin of cell to dorsum, inner margin convex medially, outer margin nearly straight; with a pair of discocellular stigmata, small and rounded; subterminal patch weakly developed; subterminal fascia grayish white; fringe pale gray. Hindwing and fringe gray. Fore leg blackish brown, tarsus yellowish brown; mid leg pale yellow except tibia ocherous brown on dorsal surface; hind leg pale yellow on dorsal surface, blackish brown on ventral surface, tarsus pale yellow.
Male genitalia (
Fig. 5
d): Uncus slightly narrowed from base to pointed apex, curved toward ventral surface. Gnathos broad at base, gradually narrowed to middle, distal half narrowed sharply, hooked. Valva broad at base, slightly narrowed to about middle; costa oblique basally, moderately concave medially; ventral margin obliquely straight; sacculus broad at base, narrowed from base to end, about 1/4 length of valva; cucullus more or less footshaped, obliquely upturned, setose, outer margin arched. Juxta shield-like, anterior margin protruded medially, caudal margin slightly concave; caudal lobe stout, digitate, as long as juxta, rounded apically, bearing setae. Vinculum narrowly banded, heavily sclerotized. Aedeagus as long as valva, curved at basal 1/3; cornutus longer than 3/5 the length of aedeagus, its basal 2/5 expanded and horseshoe-shaped distally, with numerous dentate processes spreading from 2/5 to apex, denser at about 2/5.
Female unknown.
Diagnosis
. This species is superficially similar to
D. figurata
(
Meyrick, 1910
)
. It differs from the latter by the valva with the costa oblique basally and moderately concave medially, and the caudal lobes of the juxta as long as the juxta in the male genitalia. In
D. figurata
, the costa of the valva is squarely protruded basally and deeply concave medially, and the caudal lobes of the juxta are about 1/2 the length of the juxta (
Clarke, 1965: 39, Pl. 19,

).
Distribution
.
Nepal
.
Etymology
. The specific name is derived from the Latin
hippocrepicus
(horseshoe-shaped), referring to the distally horseshoe-shaped cornutus of the aedeagus.
